Pronóstico: Highest temperature in Seoul on July 7?

Platform comparison

Market context

Seoul on 7 July 2026 will experience peak summer heat as the monsoon season intensifies, with daily highs typically climbing to 27–29°C (81–85°F) and humidity making afternoons feel significantly warmer. Historical data shows July is among the hottest months in South Korea, though August often rivals it in intensity, with temperatures rarely dipping below 21°C overnight and frequently exceeding 35°C during extreme heatwaves [1][3].

The 0% crowd-implied probability for a specific temperature range likely reflects uncertainty about whether conditions will breach the upper threshold of 31°C, which has occurred in recent years during record-breaking heatwaves, such as the 40.6°C spike in Anseong in 2025 and Seoul’s 39.6°C record in 2018 [5]. Traders should monitor the Korea Meteorological Administration’s heatwave alerts, which were raised to “severe” six days earlier than last year in 2025, and watch for tropical night forecasts, as Seoul recorded 22 such nights in July 2025—a historic anomaly [5][6].

Key catalysts include the timing of monsoon showers, which can temporarily lower temperatures but often lead to heavier downpours followed by rapid warming, and air quality reports, which tend to worsen on hotter days and may influence public health advisories [3][4]. Recent forecasts for July 2026 predict highs ranging from 80–94°F (27–34°C), with overnight lows between 72–79°F, suggesting a narrow window for extreme heat unless the heatwave persists as in 2025 [2]. Traders should also note that coastal areas like Busan and Jeju Island often exceed Seoul’s temperatures, reaching 31°C, while mountainous regions remain cooler [4].

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
